# Different behavior for Dividers in Column

I just used Column with Dividers and found the following surprising (from the documentation of Column). Here Dividers at position 2 and 3, o.k.

Column[{1, 22, 333}, Dividers -> Center]


Now

Column[{1, 22, 333}, Dividers -> {Center, Blue}]


draws all Dividers. Is this a bug or a feature?

• As Column[{1, 22, 333}, Dividers -> {Red, Blue}] reveals the first spec in {Center, Blue} refers to the column dividers and the second to row dividers. Maybe you need Dividers -> {None, {None, {Blue}, None}} to make the internal row dividers Blue? – kglr Feb 9 '18 at 10:09
• ref / Column / Details and Options: {spec_x, spec_y} apply spec_i to successive horizontal and vertical gaps. – Kuba Apr 10 '18 at 11:10

Form the Documentation, you can customize the Dividers as a feauture:

Column[{1, 22, 333}, Dividers -> {Center, {None, {2 -> Blue, 3 -> Blue}}}]

• Yes, I've seen this but for me it is a bit inconsistent. If you have something like Dividers->{...} all Dividers are drawn (an you have to suppress them, bevor drawing what you want) and in other cases only intermediate ones are drawn. – mgamer Feb 9 '18 at 9:32

In Column[{1, 22, 333}, Dividers -> {Center, Blue}] reveals the first spec in {Center, Blue} applies to the column dividers and the second to row dividers.

To get only the inner dividers in Blue, you can use the setting {None, {None, {Blue}, None}}

Column[{1, 22, 333, 4444, 55555}, Dividers -> {None, {None, {Blue}, None}}]
